The stand alone TTK installed just fine. It did not download with the Suros pack, which I was told by someone here on the forums should have been a separate download item listed on my console's HDD. I've tried deleting TTK and redownloading (many times). I've tried deleting TTK, clearing my system cache, redownloading and nothing. Chatting for ~2 hours with MS Xbox Support online through the Xbox.com's chat feature ... nothing. Posted up many times to the forums here, nothing. I'm close to my wit's end.
